To all whom it may concern.

Be it known that we, PHILIP MUELLER and ANTON C. SoIIUnnMAN-N, citizens of the United States, residing at Decatur, in the county ofMacon' and Stat-cot Illinois,.have invented new and useful Improvements 1n Self-Closing Cocks and Receptacle-Actuated Opening Means Therefor, of which the following is a specification. a

This invention relates to self-closing cocks, more part cularly to an improved structure of the cock and to mproved means foropening the same. Principally among the ObJGClLS of thls invention are-to provlde a Strong durable cock' structure of the self-closlng varlety which is compact, takes up but small space, has relatively few worklng parts and 1n which access may be readily gamed to the parts for adpistlng and renewing the same;

and to provide means for opening theuvalveof the cock by merely placing a receptacle beneath the nozzle or outlet of the cock prior to actuating the same, the opening means being provided with a guard for engagement with the receptacle to prevent the receptacle striking against the cock and chipping -or breaking and to guide the receptacle into the correct position beneath the cock for filling the receptacle. Y

Other objects and advantages of this invention will appear from the followingdetail disclosure of one embodiment of this invention, the same being illustrated in the accompanying drawings in which- Figure 1 is a vertical longitudinal section through the cock. Fig. 2 is a detail fragmentary enlarged sectional view of the lower end of Fig. 1. Fig. 3 is a transverse section 1 taken on the line 33 of Fig. 2. Fig. 4 is adetail top planview of the nozzle of the cock. Fig. 5 1s a section taken on the line 55 of Fig. 4. Fig. 6 is a bottom plan view'of the.

'. valve abutment hereinafter described. Fig.

7 is a side elevation of the'improved cock and opening means therefor showing a. receptacle about to be placed beneath the cook,

the dotted lines showing the receptacle in position beneath the cock and showing the mechanismholding the cock open. Fig. 8 is an inner end elevational view of the cock and mechanism'of Fig. 7 the-shank of the:

cock being shown in section. Fig. 9 is a detail top plan view of the guard for e gagenient with the receptacle.

The lower end of the'body'or casing 10 has an inturned flange 12 provided with' a head or raised portion at its inner edge constituting with the flange 12 a valve seat. De-

pending from the 'fiange 12 is an annular wall 13 of reduceddiameter as compared to the caslngfllO and constituting a guide as hereinafter described. Above the lianffe or valve seat'121the wall of th casing is thick ened by inwardly extendingpii ibs 14; extend ing up a short distance from the valve seat.

The casing 10- has an exterior annular formed by reashoulder 15 at its lowerend son of the reduced size of the wall or guide 13. Threaded or otherwise suitably secured to the inner .side of the casing or body 10, and adjacent to'its upper end, is a shank 16 provided with a threaded portion 17 at its nner extremity, or with any other suitable means, for attaching the shank 16 to a source of fluid supply.v The shank 16 communicates with. the interior of the casing as may be clearl' seen from Fig. 1.

\Vithin the body 10 is located a two-part Valve stem 18, 19. The part 18 is located in the upper end-of the body 10 and has an enlarged head 20 atits lower end snugly litting in the reduced portion of the casing'lO and adaptedto n1ove between the ribs 14. The head 20 is recessed in its underside to reeeivea suitable packing" 21 for seating upon the 'valv'e'seat' 12; The packing 21 is held within the head 20 by the shoulder 22 formed upon the lower stern section 19, which section has a reduced threaded portion above'thc shoulder 22 adapted to pass through the packing 21, the head 20 and into the lower end of the'stein 18 and engage in threaded relation with the head and the stem to hold the two valve-ste n sections together. The lower section 19 eiitends from the shoulder down through the valve seat 12 and carries upon its lowerend an abutment or disk '23 fitting snugly within the wall or guide 13 and havinga number of openings 24 therethrough to admit of the uninterrupted passage of the fluid'from the body 10. In Fig. 6 a bottom plan view of the disk 23 is shown and wherein it will be seen that the disk has .in its underside a diametrically extending kerf 25 adapted for the reception of a screw driver or other suitable tool for turning the lower stem section 19 in assembling and disassembling the cock.

The valve, comprising the head 20 and packing .21, is normally held closed upon the seat 12 by a spring 26 surrounding the upper section 18 of-the valve stem and bearing at its opposite ends respectively against the head 20 and the lower end of the cap 11, as clearly shown in Fig. 1. The cap 11 is hollow or is recessed as shown to' accommodate the upper end of the stem section 18 to guide the stem in its movements and to admit of the lifting of the valve from the valve seat. The stem 18 is provided witha kerf or is given other suitable formation 'to accon'nnodate a tool'for holding the upper sect ion 18 during the rotation of the lower section 19. Surrounding the lower end of the body 10 is a nozzle 27, the same comprising a sleeve having its inner diameter reduced at itslower end to snugly engage the Wall or guide 13 and to provide a shoulder 28 adapted for engagement with the shoulder 15 to limit the upward sliding movement of the nozzle upon the body 10. The lower end of the nozzle 27 has an inwardly extending annular flange 29 located directly opposite the end of the guide 13 and carrying at its inner edge in circular relation "a plurality of spaced apart fingers 30. The fingers 30 are oilset inwardly from the flange 29, as shown to advantage in Fig. 4, and project up into the guide 13 and engage the inner side thereof. The fingers 30 are thus located in-direct line with the edge of the disk or abutment 23 and are adapted to move the same when the nozzle 27 is movedup on the body 10. I,

From Fig 1 it will be noted that the shank 16 of the cock is provided with means for controlling the flow of'fluid through the shank, the means in the present instance being disclosed as comprising a screw valve 31 threaded diametrically through the shank 16 andhaving a portion of one side cut away to provide :1' recess adapted to register with 1 tl1e-.. passage through the shank 16. This screw valve 31 is adapted to be turned in order to register the recess more or less with the passage through the shank so as to regulate the normal iio-w of fluid through the cock. 'A screw plug 32 is threaded in the side l-l the-shank 16 and is adapted to bind .ceptacle strikes the lips 40.

As shown-in the against the opposite sides of the cock body 10, and being suitably'hinged thereto as at 35. I The peculiar formation of the arm 33 ofi'sets the same from the body 10' so that the body portion of the arm extends down beneath the shank-l6 substantially parallel to .the longitudinal axis of the cock body 10.

The middle portionof the lever 33 is provided with a stop 36 adapted for engagement, as shown in Fig. 7, with the inner side of the body 10 or nozzle 27. The lever 33 projects down from the nozzle 27 and carries upon its lower end a guard such as shown in detail in Fig. 9. This guard comprises an arcuate strip 37 conformin substantially to the shape of one side 0 a receptacle, "such as the glass shown at 38 in Figs. 7 and 8, and lies in a substantially vertical pla ne.. The. strip 37 is provided near its opposite ends with a pair of fingers 39 rising to ,a point near the lower end of the nozzle 2-7 and being there turned outwardly te provide; projections or lips 40 adapted to ngage the upper edge of the receptable 38and g'prevent the movement of the receptacle above the lips.

The upper forked end of the reversely formed E-shaped lever 33 connects at a point spaced inwardly from its pivotal connection 35 with the body 10, to the nozzle27 bylinks 41. The links l1 are hinged attheir lower ends upon the opposite sides of' the nozzle 27 as at 42 and are hinged at their upper ends to the arms 34 of the lever 33 at points indicated at 43.

In operation fluid passes through the shank 16, its flow being regulated by the screw valve 31,. into the body 1.0 of the cock. Normally the spring 26 holds the valve 20 to its seat l2 and the fluid is thereby prevented from escaping from the body.

From Fig. 7 it will be noted that. when it is desired to draw cilia quantity of fluid through the cock into the receptacle 38, -the latter is placed against the guard or strip 37, the receptacle3S being moved up toward the nozzle 27 until the upper edge of the re- A pressure is now exerted upon the receptacle 38 to force it back under the nozzle 27 into the position disclosed in dotted lines in Fig. 7. This movement'swings the lever 33 hack vardly and turns the lever upon its pivotal supports 35 whereupon the links 41 are raised and cause the nozzle 27 to be-drawn up upon the body 10. The position of the lever and the links-in this latter position is shown in dotted lines in Fig. 7.

lVhen the nozzle 27 is thus raised the fingers 30 of the nozzle move up in the guide 13 and strike the abutment 23,carrying the abutment up upon the further movement of the nozzle. The abutment 23 lifts the twopart valve stem against the tension of the spring 26 and thereby raises the valve 20 from its seat 12.. Fluid in the body now' passes down about the sides of the valve head in the chann el'sbetween the ribs 14, the fluid "passing down through the valve seat, the'openings 242 111 the abutment 23, and finally out through the lower end of the nozzle 27 into the receptacle. As soon as the desired quantity of fluid has been drawn off the receptacle 38 is drawn away from the strip 37 and the lever 33 by its own weight, drops back into the normal position shown in full lines in Fig. 7and the. valve is automatically closed bythe spring 26. The stop 36 limits the forward swinging movement of the lever 33 and holds the nozzle 27 from falling from the body 10. It will be noted from Fig. 7 that when the receptacle 38 is pushed up against the lips the glass is guided into its proper position beneath the nozzle 27 by merely pushing inwardly upon' the glass since the lever is so hinged as to slightl} raise the guard and Carry the glass up about the lower end o'fthenozzle 27.

lVhat. isclaimcd is- 11 In a self closing cock, a movable nozzle for opening the cock, a lever hinged to the cock, a guard carried upon the end of the lever beneath the nozzle adapted to receive a receptacle and guide the same into position beneath the cock, and links connecting the nozzle to the lever whereby the movement of the lever raises said nozzle to open the cock.
